RE: [Fwd:[Axis2] WSRF Implementation]

["Hawkins, Joel" <Jo...@compuware.com>]

Update on the WSRF saga - from the Muse mailing list. 

<snip>
We are currently looking at merging the three Apache projects (WSRF, 
Pubscribe and Muse) into a single entity under the Muse project.  While 
I have done some work on this there have been other things happening 
which have made me reconsider the project as a whole.

We have been talking with a team at IBM, whom we work with through the 
spec committees, to do a joint next-generation implementation of WSDM, 
and its sub-specifications.  The implementation would not only position 
the WSDM effort in a more future-proof way (i.e. move towards WSDM 2.0), 
but continue to move the project forward in a positive direction.  IBM 
has code which they would like to contribute as the foundation for this 
effort.  The code will initially be run in Axis2 which would please 
those who are seeking an Axis2 implementation of WSDM (WSRF,WSRN, etc).  

IBM is willing to contribute base code, which will be reviewed by us, 
and developers to the effort.  IBM would like to be part of moving the 
Apache WSDM effort forward, and is excited about the possibilities of 
being part of the project.  They are even planning on contributing 
tooling around this effort to the Eclipse Project.

I believe this to be the right thing to do for the direction of the Muse 
project.  Bringing IBM to the project will entice more users, generate 
more interest in the project and bring more active committers moving the 
effort forward.

Here is my +1 for this effort.  I hope others will join me in support of 
this.

I apologize that I have not been forthcoming thus far, however I had to 
consider the legal side of things before making any statements regarding 
this.
</snip>

Part of this effort will be carried out in conjunction with the Eclipse TPTP
and Corona projects, which will have the additional benefits of bringing
Apache and Eclipse closer together, and injecting the Axis2 stack into the
OSGi platform. Pretty exciting stuff, at least to me!

Cheers,
Joel Hawkins

Steve,

Funny you should mention those features - they're exactly what we're doing
for integrating WSRF with our Corona project! I'll take a look at smartfrog
- thanks.

Sanjiva, I'll check in with Muse and WSRF to see if anyone over there's
contemplating an implementation.

Cheers,
Joel

I have hints of a WSRF app on the smartfrog repo, but its all LGPL so 
you can't use it.

What you could do is look at the architecture which has the following 
features
  -uses URIs to index things, not the fancy (and unstable, less 
interoperable) WS-A reference props/params
  -doesnt have a simple resource -> object binding. Instead each 
endpoint gets to provide its own mapping code, which is useful for a 
high availability solution where state can be stored in a db, 
tuple-space or whatever.
  -does not use xmlbeans, but works at the Axiom level. Keeps it 
lightweight.

The thing to remember is that although you could export object instances 
as WSRF endpoints, you shouldn't. distributed object applications have 
known failures, which we don't want to reimplement.

Not looked at muse; don't know its current state.

Wow interesting indeed .. Axis2 appears to be penetrating deeper in
places we didn't know about ;-).

I hope that the Muse folks realize they can't just suck in a bunch of
code from IBM .. it needs to go thru the incubator.

Sanjiva.
